During operation
Once LIMAX Safe SG/SC was commissioned correctly, it is only in the following cases that any necessary opera-
tions are required on LIMAX Safe SG/SC:
Readjustment of floor levels (only if necessary)
Emergency evacuation and troubleshooting if a safety function has been triggered or in case of defects
of the system itself (only if necessary)
Setting the parameters (only if necessary)
Examination of the elevator by the notified body (after commissioning and then annually)

Relay Test
The OC and SGC contacts are normally always closed. NOC may be closed for a long time (depends on im-
plementation of door bridging in the lift control and on lift operation). The cabin may stay on a floor with open
doors for a long time. Therefore a periodic test, forcing the relays to switch, has to be implemented.
The lift control may demand a relay test by sending the corresponding CAN message (
/CO_SPECS/) when-
ever it wants to do this, but relay test has to be carried out latest after 12 h after the last relay test.
In case 11 h elapsed since last relay test LIMAX Safe SG/SC reminds the control (by periodically sent
CAN message) to carry out the test (
In case 11 h 50 min elapsed since last relay test LIMAX Safe SG/SC decides on his own when there is a
suitable moment to carry out the test (at next standstill).
In case 12 h elapsed since last relay test, LIMAX Safe SG/SC carries out the test regardless of any mov-
ing activities.
The last two conditions are only for safety reasons. Normally lift control should always decide about the moment
for the relay test because the control can better know when a relay test is possible without disturbing the normal
lift operation.
During relay test all relays open for a short period of time and the level change of their feedback lines are
checked. Additionally, the level change of
8.3.12.1 (this applies only to the SG variant).
